Jacek Gwizdka:
RESEARCH KEYWORDS
RESEARCH FOCUS
 

My goal is to contribute to our understanding of the fundamentals of human-information interaction. My research crosses disciplinary boundaries and can be described as cognitive psychology of information interaction. It is situated at the intersection of interactive-information retrieval (IIR) and human-computer interaction (HCI) - recently termed human-computer information retrieval (HCIR). My work is influenced by theories and methods from cognitive science and cognitive neuroscience and by techniques and tools from brain-computer interfaces and neuro-physiological computing.


My scholarly goals are achieved through several related projects. (see a more complete list of my publications | CV | | GoogleScholar | Academia.edu | ResearchGate | Orchid ID | Researcher ID

Cognitive Load | 2008-
 
Cognitive Load in Search

Cognitive Load (CL) is considered an important component of 'difficulty' in information tasks. In this research theme I study CL in distinct search task stages, the effects of search user interfaces on CL. Cognitive abilities are considered as factors mediating the search task performance.
Another aspect of this research is concerned with CL measurement: after task | during task and objective | subjective. Most recently, I use neuro-physiological measures to infer cognitive and affective states (e.g., eye-tracking and EEG).
